Export to MIDI File
===================

*Example script* (scamp): `examples/Notation & engraving/Basics/record_and_export_midi.py <https://github.com/MarcTheSpark/scamp/blob/main/examples/Notation & engraving/Basics/record_and_export_midi.py>`__

*Download:* :download:`record_and_export_midi.py <downloads/notation_engraving_basics_record_and_export_midi/record_and_export_midi.py>`

Records glissandi with microtonal pitches and playback params (fast-forwarded), then exports the performance as a MIDI file.
